Compiling on macOS fails about fftw HOT 2 CLOSED

You can get around this by:

1. Installing fftw via some other mechanism (e.g. brew install fftw if you use homebrew).
2. Using the "system" library feature when depending on fftw:

[dependencies.fftw]
version = "^0.5.0"
default-features = false
features = ["system"]

I believe the default-features = false bit is unnecessary but I think it makes it a little more explicit what the intention is.

I have the same problem, @duane's advice to use system feature helped me to make it work with fftw = "0.6.0"

I tried to dig this problem and found that I can successfully execute this ./configure ... command inside FFTW source downloaded by fttw-src. If I manually reproduce actions fftw-src's build.rs does (download source, unpack and execute ./configure ...) then everything works fine too. config.log files are virtually identical in both cases and differ only by some random paths which change from run to run, both config.log ends with configure: exit 0. Probably it is some problem in environment variables or such kind of stuff which can differ between running from Rust and terminal.
